Product Description

When a high-fault panel simply needs a solid 4-pole main breaker without extra protection layers, the 3VA2063‑6HL46‑0AA0 fits right in. It combines 85 kA H-class breaking with an ETU320 LI trip unit, delivering essential overload and instantaneous short-circuit protection through straightforward clamp terminals.

Protection Functions

Overload (L): Ir = 25…63 A, I²t characteristic, delay tr = 0.5…17 s.
Instantaneous (I): Ii = 1.5…12 × In (95…756 A).
Neutral (N): Adjustable OFF or 100% of In.

No communication, no ground-fault monitoring—just reliable tripping when it counts.
